l AGRIGULTUBALIMPLEMEN'I Application led March 14, 1930. Serial No.435,809.

Our invention relatesbroadly yto agricultural implements' and :has to domore particularly with devices known as beet pullers.

An object of our invention is to provide a debecome apparent to thoseskilled in the arty as the description proceeds.

YReferring now to the drawings forming part of the specification vandillustrating ra preferred embodiment oflour invention n Fig. 1 isalongitudinal sectional view of aldevice embodying our invention, most ofthe parts being shown linfelevation;

Fig. 2 is a fragmentary perspective'view on an enlarged scale of ourimproved pole Fig. 3 is a similar different position; Y Y l n Fig. 4 isa top plan view-of a portion of view koi the same, in a 12-12'connectedby suitable means includj whichV is pivoted a'rod19 which, in turn, isy

ing a bearing 15 journaling a U-shaped yoke 18. This yoke carriesadjacent the lower extremities of its legs a pair of plates which areadaptedto penetrate the. ground, when adjustedfor4 such operation, forthe kdigging up of beets or therlike. Mounted on each leg of the yoke 18is asleeve 18 to threaded intoa bracket 19 which; ispivotally secured toone of the frame members 12. Theelevation of the digging plates 20 maybe adjusted by shifting the sleeves 18 longitudinally of the legs of theyoke 18.v

The bars12 are connectedat their forward end by means of asuitablebracket 21.*which includes sleeve portions22 journaling a pairof steering columns 23, to the lower ends of which are j ournaledsteering. wheels 25. The upper end of each of thecolumns 23 carries anear 26 toy which is secured a rod 28, the other end of which is securedto a foot steering member 30. This foot member is pivoted j adjacent itsmidpoint to a bracket 32 which, in turn, is secured yto the member 15.vA substantially V-shaped member 35 is perforated adjacent the ends ofthe legs of the V, the rods 28 passing through these perfora- Y tions soas to secure kthe member 35 to the foot member 30 while the vertex ofthe V is perforated to form an eye forreceiving a helical tension spring37. Thefother end of this spring is ,secured toa hook 38 attached to abracketj39 which in turn may be mounted on the member 15. A seat 40 ismounted on a` bracket 142 which convenientlyfmay be a continuation ofthe bracket 32, andl it will be apparent that a person sitting in theseat 40 mayl Secured to each of the frame members 12. is asuitable'bearing 45 inwhich is rotatably, journaled anadjustable arm orbracket Y46 carrying a disk 48. Y

.i A pair of wheels 50 is rotatably journaled upon a Ufshaped axle rod52 which'is journaled in bracketsr 55 mounted on they frame members 12.The cross portion 57 of the U-bar 52 extends through a pole lockingmember'indicatedgenerally, at 58 whichcomprises Y a loop member 59,preferably a casting, to which is secured as by means of bolts, and nutsorthe. like a] co-operating member 60, the'memberi being keyedr as at 61to the U- member 57.' Y

A hitch is provided for the device by means of a tongue 63 which ispivoted to the frame as at 65, thistongue'carrying a U-shaped bracket 67which, as best shown in Figures 2 and 8, preferably is curveddownwardly, and as shown in Figures 4 and 5, is more than large enoughto receive the loop 59 of the lock 58, so as normally to permit anglingof the tongue with respect to the frame when the former is unlocked. Apin 68 connecting the sides of the U-shaped bracket 67 serves as apintle for a locking member 70 Which has laterally extendingbifurcations 72,` and extend ing oppositely from the bifurcations 72.isa loop member 73 in Which is journaled a mani ulating member 75. v Y

` ecured'to each'fthe'sleeves 22 is a hook 77 to whichY is connected ahelical tension spring 78 which in turn is connectedito a hook l80pivotcd to sleeves 82, these sleeves being adjustably securedv upon thelegs ofthe U-shaped axle 52.

The'axle 52 may be providedwith any suitable means for adjusting theelevation of the wheels 50,-which may include abraeket 85 connectedasbymeansofl a link'S to a suitable'hand lever 87, the latter'beingpivotedat its lower end to one of the bars121and adjnstably securable invarious positions by meansof a dog engageable with. anarcuate raak 89.

lItiwill be seen that when the locking device 70 is out of o nativerelation with the'loop 58 asshown in? *ig. 2, the tongue 63-mayi beanledrelative to theframe in view of the play tween theQU-member 67 andtheloop 59. However, yWhenfit is desired to make the hitch absolutelylrigidiwith respect' to the'frame, the lockinglmember-70 isarrangedasrshown in Figures'vand 5 withthe bifurcatedmember 'Z2engag'ing the1001159. Itralso will beapparenti that such a Erigid connection may i bemade 'regardless of the elevation ofthe digging. members 20, since the;loop 59 willbeengageable' byt the bifurcated lock 72. for anypositionofadjustment of thewheels. 1 Obviously, adjustment of the Wheels 1in avertical planebymeans ofthe leveri87 vwlll have thesame e'eetrto varythe relation of the digging members to the ground-surface as if7 thedigging! members 20 were` vertically adjusted.

:It'will be seenfthatby providing'thelockingmeans 58 on'theaxle 57 faparticularly simple and economical constructionis provided, eliminatingthe necessity for special means xm'ounting the tonguedocking device.
